Document Summary

Peripheral nervous system: brain, spinal chord, somatic system: spinal nerves, visceral system (autonomic nervous system) Medial (midline): cut it in half and look at the middle. Coronal (frontal): cut vertically through your head. Posterior/ caudal: behind or toward the back. Midline: towards the central axis of the body. Parts of the central nervous system (brain and spinal chord): Cerebrum and cerebral cortex midline: 2 hemispheres divided by the sagittal fissure on the, concerned with contralateral sensation and movement, also has 2 hemispheres. Brain stem: concerned with ipsilateral motor control, most primitive part of the brain, concerned with life functions (respiration, body temperature) Spinal chord: channel for information to and from the brain, sensory and motor losses following sensation. The brain has grey matter on the outside, white matter on the inside. White matter is where axons live, myelin is white matter too.
